IMPROVEMENT IN CORN-SHELLERS.

Specification forming part of Letters Patent No. 204,653, dated June 11,1878; application tiled March 18, 1878.

To all whom it may concern:

Be it known that I, THOMAS BRENNAN, of the city of Louisville, in thecounty of J efferson and State of Kentucky, have invented a certain newand useful Improvement in ()orn- Shellers; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming part of thisspecification, and to the letters of reference marked thereon.

Figure 1 is a perspective view of the machine with the cover and side ofthe feed-box left out to show the interior arrangement of the severalparts. Fig. 2 is a perspective view of the mouth piece, showing thespring and hinged pressure-bar. Fig. 3 is a sectional view of themouth-piece, showing the arrangement of the spring and hingedpressure-bar. Fig. 4 is a perspective view of the end plate of the box,showing its connection with the dischargeopening.

This my invention relates to a new and useful improvement incorn-shellers, consisting in a hinged pressure-bar, adapted to hold theear against the sheller-disk.

In the drawings, A A represent the frame, which is made of wood, and inform as shown in the drawing. B is the sheller-disk and driving-wheelcombined, and G is the pinion by which it is driven. This pinion is castsolid on the disk to save cost in fitting. D is the driving-pinion, andE is the toothed shellerwheel. F is the mouthpiece or hopper, which ismade in form as shown in the drawing. G is the pressure-bar, for holdingthe ear of corn against the wheel. This bar is hinged to the mouth-pieceF by means of hook R at the top, which catches over a fulcrum-pin formedin a raised projection on the mouthpiece flange at the back, or may, ifmore suitable, be hinged by a bolt through i and the jaws of the flange,or its equivalent. This pressure-bar is formed with stops a, which bearagainst the edge of the hopper, and servetohold said bar in properposition with relation to the hopper, preventing displacement andsidewise movement. H is a spring at the back of the bar, one end ofwhich passes through said bar near its center, and is made to restagainst its lower edge as a fulcrum, while the other end extends up to2. lug formed on top of the mouth-piece, where it is held in position bymeans of a thumb screw, 1. This thumb-screw serves for regulating thepressure on the bar, and also for permitting the detaching of the springwhen the pressure-bar is to be removed. J is the metal end plate, withdischarge-openin g formed in it, the two cast in one piece, and in formas shown in the drawing. These plates are intended to confine andstrengthen the ends of the feed-box and dischargeopening, where unusualstrength is required. K is the dischargeopening, and L is one of themetal end plates, which plates are secured to the box by means ofscrews. N N are the top rails of the frame, which are framed togethernear the ends, leaving suflicient projection to form handles P P P P onthe ends, for convenience in handling the machine. Q is the crank bywhich the machine is operated.

Having thus fully described the nature and object of this my invention,whatI claim as new, and desire to secure by Letters Patent, lS--- 1. Thecombination of a hinged pressurebar and a spring, the latter extendingthrough and bearing upon the former, substantially as shown anddescribed.

2. The combination of a hopper, a pressurebar forming one side thereof,and provided with stops and a spring, substantially as and for thepurpose described.

3. The combination of the flanged hopper provided with a fulcrum-pin,the perforated pressure-bar formed with a hook at its upper end, and thedetachable spring extending through its perforation, substantially asand for the purpose described.
